6. Operating Instructions
The Jesverty SPS-1362 offers both fixed and adjustable voltage output modes.
6.1. Fixed 13.8V Output Mode
- Ensure the power supply is connected to AC power and turned ON.
- Set the 13.8V Fixed/Adjustable Voltage Switch to the "13.8V" position.
- The digital display will show "13.8V". The Voltage Adjust knob will be inactive in this mode.
- Connect your device to the main output terminals (Anderson connectors) or the cigarette lighter socket. Ensure correct polarity (Red for positive, Black for negative).
6.2. Adjustable 9-15V Output Mode
- Ensure the power supply is connected to AC power and turned ON.
- Set the 13.8V Fixed/Adjustable Voltage Switch to the "ADJ" (Adjustable) position.
- Use the Voltage Adjust Knob to set the desired output voltage between 9V and 15V. Observe the digital display for the current voltage setting.
- Connect your device to the main output terminals (Anderson connectors) or the cigarette lighter socket. Ensure correct polarity.
